Below you will see a list of organizations that teach global citizenship education.
In today’s world, learning the ability and skill to communicate with others across cultural, religious, and other differences is a concern no longer only for the elites; instead, acquiring global citizenship competencies has become essential for everyone.
You can read more about the rationale for teaching and learning global competence and about the qualities of globally competent students in Veronica Boix Mansilla and Anthony Jackson's Educating for Global Competence: Preparing Our Youth to Engage the World from Asia Society (2011) here.
There is also a rich compendium of resources available through UNESCO's website about global citizenship education.
